Method for optically scanning and measuring a scene

A method for optically scanning and measuring a scene by means of a laser scanner, which, for making a scan which shows a certain center, optically scans and measures its environment which is provided with targets, whereby two adjacent scans having different centers and scanning the same scene overlap within a range of measuring points, so that at least some targets are scanned by any of the two scans, the method comprising the steps of:

• registering the two adjacent scans by localizing the targets in the measuring points of the two adjacent scans, in order to subsequently identify them;
• looking for candidates of correspondence among the localized targets of the two adjacent scans;
• and
• performing a test registration of the two adjacent scans, wherein if there is a sufficient compliance of the measuring points within the overlapping range, the test registration is taken over for registration, thereby identifying the targets.
